Download folder structure of your entire SiteBar to a file. Import this file to your bookmarks.
Each folder is represented by a Live Bookmark. This way your bookmarks will be integrated among
your other bookmarks, but folder content will be online downloaded from SiteBar.
In case a folder has subfolders, content of the actual folder will be shown in @Content folder.

If your browser does not have a sidebar feature, you may use this bookmarklet*.
It will open SiteBar in a pop-up window similar to a sidebar. Please be aware of the fact
that your browser may block pop-ups!

Visit the portal, find a place where you can add content. Copy there this URL https://beta.sitebar.org/iframe.php
and a new gadget should be created (note that https is usually not supported by portals,
you may, however, use https in the iframe.php). Note that your username/password is NOT
exposed to the portal. MS IE users may need to allow cookies for the SiteBar server domain.
